,, to bottleswhere the coking shoulders are ira row oflockin scallops, or crimp's at the I they are produced As a res regular in thickness, or to bottles having shoulders which vary in thickness.

' In applying the crown seal to bottles, it is supposed that all bottles will have the looking s oulders uniform in thickness throughout their extent, and that the shoulders on the different bottles will not vary in thick ness. As a matter of fact, however, it is almost im ossible to get bottles with uniform locking oulders owing to-the way :in which t -where caps are used with a solid, or; un vided skirt, with lower edge, should the locking shoulder be less in thickness than the standard size, when the capping head descends upon the seal in applying it to a bottle, the crimps or scallops w1 t e and after these have been compressed 'ud. .pressure, the cork will not readilyexpand,

be forced down below the under side of shoulder, and will not engagethe same until pressure is removed from the seal by the liftmg of the pressure block, akwhich time the seal will return until the scallops engage the shoulder, and hold, the capagainst further rising. Here, though, is the cause of serious' trouble from the fact that cork disks are-u ally used for gaskets withinthe' met and even a slight return of the cap owing to the carrying down too farof-the scallops, will be sufficient to cause a loss of some gas, although it may pass off so graduallythat if the contents are used within a short time the loss will not be entire. Should, however, there be. any considerable return of the cap,

-- the gas will be entirely lost,and the contents of the bottle will be 0 no value. If the looking shoulder-is thickerjhaz-nthe standard, the

scallops will not carry down far enou h to blowofi immediately on the return of the capping head, causing the loss of the seal,

tle. Or, i the shoulder is but slightly above the standard, the scallops may catch slightly,

it often happens that the locking shou ders are less in diameter thanthe standard, and where the skirt of the cap is undivided, the capping head will not force the same inward against'the shoulder to cause a tight seal. .4 It is the object of. my invention to provide conditions, and adapted itself to bottles havness, w-het er less, or greater than the standwhere they are less in diameter than the standard.

A further object of my invention is to pro' vide a, seal which can be easil removed from lialiilityof breakage inthe removal of the sea. l I

My invention is illustrated in the 'f accome panying drawing, in which Figur seal applied to a bottle of standard size; Fig.

Fig. 3. is a side elevation of a bottle havin a locking shoulder irregular in thickness, and a central vertical section of my seal applied thereto; Fig. 1. is a blank stamped from sheet metal from which I form my improved sealing cap; Figf, 5.-is a view of the 'same .drawn into shape preparatory to-noilingthe view of a seal formed therefrom.

In the accompanying drawing, the several parts of my invention are ind cated by nu a seal, preferably formed from a b ank as shown m F 1g. 4, which is stamped from sheet shown in Fig, 5, and then into the shape shown in Fig; 6. The blank consists of acentral part 9, which in the preferred shape 18 lock underneath the same, and the seal will aiid the contents may be lost later. :A ain,-

the bottle and eliminate to a arge exteht'the e 1. is a side elevation of my improved 2. is a central vertical section of the same;

- wings; Fig. 61 1s avicw' n veil-tidal s'e *tioliici'f.

the seal, with-the wings coiled preparatiii'yto {mounting on a bottle; FigE' Y. is'fa viewoffa modified form of blank; and"l ig 8.is a'plaii morals of reference; and'in practice I provide metal, and drawn in the press into the shape to the part it, they are ooilod outwardly and oireular in form, and a plurality of radial wings It). The tllfili il is proportionod in size so that when drawn into the shape shown lll Fig. 5, the wings will he ionding with the upwardly, as shown in-l ig. (3, tho. wings being eoiled until vtl'uijuppor tangential point. is nearly on a level with the top of tho. oap,

leaviin enou h ol' the skirt uneoilod to l'orni a soeuro seat for the eork disk l3, forming the paoking.

In applying the. seal to a bottle, as [4, an ordinary oapping head may he used, snehas used in applying the orown soals", al

though I prol'or to use a eapping head with a throat loss taporod than used in applying the orown. As the eiqipi'ng hoad doseends, the eoiled wings It) will ho unooiled by tho downward pressure ol' the throat and the hack prossuro oi the looking shoulder L"), of the bottle, eausing tho. wings to oontaet very elosely with tho looking shoulder and eonlorm themselves thoroto until a sullioiont part of oaoh wing is unooilod to allow the roinaining part of tho ooil, as It), to ontor the groove IT, in tho nook ol' tho lmtt lo, t he wings It) being made ol' sullioiont. longth so that the u'nooilod part H3 will represent at loast a eoinplote turn of tho uiotal whonit is seated within tho. groovo IT in ordor to give sullieient rigidity to tho wings whon in looking engagement with the looking shoulder 15.

As tho wings It) are independent ol'oaoh other, and tho un'rollilurol' thoooils is oll'ortod by tho eapping head in oonjun'rtion with the shoulder l5', onl so muoh ol' the ooil will he unrolledas is absolutely nooossaev to allow the ooil Hi to enter tho groove l7, as-it will then ho impossililo tor the .oapping head to continue to unroll tho ooil whothor t ho looking shouldor ho loss in thieknoss than the standard or greater inJ'iii-knoss; and as those wings are indepolnt ol' oaeh other, should thelooking shoulder 15 he irregular in shape.-

as shown in Fig. it, tho sido 18. being thicker than tho side It), only so much ol' eaehooil will he unrolled as is necessary to allow tho remaining part to enter the groove below the looking shoulder; and when the eapping head is removed, there is no danger of the cap returning to oauso a leakage either of liquid orgas.

it will thus he soon that I have provided a seal in whioh the looking shoulder itself terms a part in adjusting the seal, and it the tonsion ol' the 'prossuro hlook is sullieient to oauso the proper embedding of the lip of the bottle in the gasket when the seal is applied, it will he held so omhoddod until the seal is removed no dill'erenoo how irregular the looking shoulder, or how much it varies from tho standard. Then, too, in removing V tho. soalwith the tools ordinarily used in removing the ferownf, as the-wings are separated, from eaoh other, the particular wings engaged by the tool will he raised outwardly, and rolled, or partially rolled upwardly, so that the seal leaves the bottle with more of a rolling'motion than with theslidingmotion roquirod whorethe skirt of tho. oap is undivided, as will 'he readily understood. This not, only'm'akes the removal of'the seal much easier, but reduces the liability of breaka e.

ln l ig. 7 .1 have shown a square blank, and in Fig. t a can formed from the same with tho oorners rolled up to form the coils. Cutting tho blanks out in this way causes no loss of metal whatever.

Having thus dosorihed-my invention, what I elaim as now and desire to secure by Lettors latont of the United States, is
